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

We show that the coercive field in ferritin depends on the maximum magnetic field in a ysteresis loop and that coercivity and loop shifts depend both on the maximum and cooling fields. The time depend...
