Size induced change-over from first to second order magnetic phase transition in La0.67Ca0.33MnO3 nanoparticles

Tapati Sarkar, A. K. Raychaudhuri

In this report we show that in the perovskite manganite La_{1-x}Ca_{x}MnO_3 for a fixed x \approx 0.33, the magnetic transition changes over from first order to second order on red…
