Magnetic hysteresis behavior of granular manganite La${}_{0.67}$Ca${}_{0.33}$MnO${}_3$ nanotubes

M. I. Dolz, S. D. Calderón Rivero, H. Pastoriza +1

A silicon micromechanical torsional oscillator is used to measure the hysteresis loops of two manganite La_0.67Ca_0.33MnO_3 nanotubes at different temperatures, applying an externa…
