Magnetic Domain Wall in undd 3He

Metastable magnetic domain wall dynamics

The dynamics of metastable magnetic domain walls in straight ferromagnetic nanowires under spin waves, external magnetic fields and currentinduced spin-transfer torque are studied by means of micromagnetic simulations. It is found that in contrast to a stable wall, it is possible to displace a metastable domain wall in the absence of external excitation. In addition, independent of the domain w...

Magnetic diffraction in solid 3He

2014 Magnetic diffraction in a bcc single crystal of 3He directly proves the occurrence of an antiferromagnetic ordering with a propagation vector ( 1 /2, 0, 0). J. Physique Lett. 46 (1985) L-923 L-927 ler OCTOBRE 1985, Classification Physics Abstracts 67. 80 75 . 25 75. 30E The originality of the magnetic ordering of solid 3 He is that the large zero point motion leads to atom-atom exchange pr...

Universality classes of magnetic domain wall motion.

We examine magnetic domain wall motion in metallic nanowires Pt-Co-Pt. Regardless of whether the motion is driven by either magnetic fields or current, all experimental data fall onto a single universal curve in the creep regime, implying that both the motions belong to the same universality class. This result is in contrast to the report on magnetic semiconductor (Ga,Mn)As exhibiting two diffe...
