Magnetic core loss of ultrahigh strength FeCo alloys
(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
(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
(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
(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
(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. ...
