    Studies of deposition order anomaly of exchange coupling in bilayers and trilayers of NiFe and CoO 

    Ambrose, T.; Leifer, K.; Hemker, K. J.; Chien, C. L. (American Institute of Physics, 1997-04-15)
    The temperature dependence of the exchange field and coercivity and the effect of deposition order have been studied in a series of bilayer (NiFe/CoO and CoO/NiFe) and trilayer (NiFe/CoO/NiFe) films. A profound difference ...

    Comparison of surface spin wave modes at Fe/MnF2 and Fe/Mn interfaces 

    Siu, I. L.; Islam, M. N.; Walker, J. C. (American Institute of Physics, 2000-11-01)
    We have studied the thermal demagnetization in semi-infinite ferromagnets in Fe/MnF2 and Fe/Mn bilayers using Mössbauer spectroscopy. We find that the hyperfine field at the Fe/MnF2 interface follows a quasilinear temperature ...

    Magnetic properties of one-dimensional quasiperiodic Co/Pt multilayers 

    Zhu, L.Y.; Cheng, X.M.; Chien, C.-L. (American Institute of Physics, 2006-04-15)
    We have fabricated Fibonacci [Co/Pt] multilayers with two constituent Co/Pt bilayers, as well as periodic multilayers of the same Co/Pt bilayers, all of which exhibit perpendicular magnetic anisotropy. Magnetic properties ...

    Exchange coupling between Cr and ferromagnetic thin films 

    Yang, F.Y.; Chien, C.-L. (American Institute of Physics, 2003-05-15)
    Exchange bias has been observed in Ni81Fe19/Cr bilayers. The exchange bias field for Cr thickness tCr larger than 62 Å increases with tCr and levels off at tCr=150 Å, whereas coercivity increases without saturation. The ...

    Cell manipulation using magnetic nanowires 

    Hultgren, A.; Tanase, M.; Chen, C. S.; Meyer, G. J.; Reich, D.H. (American Institute of Physics, 2003-05-15)
    The use of magnetic nanowires is demonstrated as a method for the application of force to mammalian cells. Magnetic separations were carried out on populations of NIH-3T3 mouse fibroblast cells using ferromagnetic Ni wires ...

    Magnetic core loss of ultrahigh strength FeCo alloys 

    Cheng, X.M.; Zhang, X.K.; Zhang, D.Z.; Lee, S.H.; Duckham, A.; Weihs, T. P.; Cammarata, R.C.; Chien, C.-L. (American Institute of Physics, 2003-05-15)
    Hiperco® 50 alloy heat treated between 450 and 650°C exhibits superior mechanical properties. We report the measurements of the ac core loss at various frequencies up to 4500 Hz of the Hiperco® 50 alloy samples annealed ...

    Current and shot noise measurements in a carbon nanotube-based spin diode 

    Merchant, Christopher A.; Markovic, Nina (American Institute of Physics, 2009-04-01)
    Low-temperature measurements of asymmetric carbon nanotube (CNT) quantum dots are reported. The CNTs are end-contacted with one ferromagnetic and one normal-metal electrode. The measurements show a spin-dependent rectification ...

    Long-range exchange coupling between a ferromagnet and an antiferromagnet across a nonmagnetic spacer layer 

    Gokemeijer, N.J.; Ambrose, T.; Chien, C.-L.; Wang, N.; Fung, K.K. (American Institute of Physics, 1997-04-15)
    The antiferromagnet/ferromagnet exchange coupling giving rise to a shifted hysteresis loop has usually been considered an interfacial effect. We show evidence that this exchange coupling between an antiferromagnet (CoO) ...

    Dependence of exchange coupling on antiferromagnetic layer thickness in NiFe/CoO bilayers 

    Ambrose, T.; Chien, C.-L. (American Institute of Physics, 1998-06-01)
    A systematic study of the dependence of exchange coupling in NiFe/CoO bilayers on CoO layer thickness tAF from 5 to 500 Å has been made. For large CoO thicknesses (tAF>100 Å), the exchange field varies as 1/tAF, whereas ...

    Doubly exchange-biased NiCoO/NiFe/Cu/NiFe/NiCoO spin valves 

    Ambrose, T.; Liu, K.; Chien, C.-L. (American Institute of Physics, 1999-04-15)
    A new type of doubly exchange-biased Ni50Co50O/NiFe/Cu/NiFe/Ni30Co70O spin-valve structure, with two ferromagnetic layers exchange biased in opposite directions by two different antiferromagnetic layers is demonstrated. ...
