Abrupt field-induced transition triggered by magnetocaloric effect in phase-separated manganites

L. Ghivelder, R. S. Freitas, M. G. das Virgens +7

The occurrence at low temperatures of an ultrasharp field-induced transition in phase separated manganites is analyzed. Experimental results show that magnetization and specific he…

Low energy spin wave excitations in bilayered magnetic manganite La $_{2 - 2 x}$ Sr $_{1 + 2 x}$ Mn $_{2}$ O $_{7}$ ( $0.30 \leq x \leq 0.50$ )

H. Martinho, C. Rettori, D. L. Huber +2

We have studied the low-temperature behavior of the magnetization and the specific heat of the bilayered perovskite system , for $0.30\leq x\leq 0.…
