Abstract:
Magnetic ceramics are important materials for a variety of applications such data storage, tunnel junctions, spin valves, sensors etc. These materials possess extraordinary properties at reduced dimensions. The properties of nanostructures are governed by finite size of the particles, lattice distortions and grain boundary effects. In the first part of this lecture the structure-property correlations of Pr1xCaxMnO3 (PCMO, 0.0 < x ≤ 0.5) nanoparticles (NPs) will be discussed. Although PCMO at x < 0.1 is conventionally antiferromagnetic (AF), ~40 nm diameter PCMO NPs demonstrate ordering of Pr spins below 50 K with x < 0.04. Even in absence of Ca2+-doping, ~35 nm PrMn0.9O3.01 NPs show ferromagnetism below 100 K due to the increase in
