Shifted loops and coercivity from field imprinted high energy barriers in ferritin and ferrihydrite nanoparticles

N. J. O. Silva, V. S. Amaral, A. Urtizberea +8

We show that the coercive field in ferritin and ferrihydrite depends on the maximum magnetic field in a hysteresis loop and that coercivity and loop shifts depend both on the maxim…
