Low temperature magnetic behaviour of glass-covered magnetic microwires with gradient nanocrystalline microstructure [PDF]

, 2014
Slow nanocrystallization driving dynamics can be affected by the combination of two factors: sample residual stresses and sample geometry. This effect is evidenced at the initial stages of nanocrystallization of amorphous CoFeSiBCuNb magnetic microwires.
