We investigated the Co substitution effect for the magnetic properties in room-temperature ferromagnetic oxide Sr3.1Y0.9Co4O10.5. The substituted element (Al and Ga) and low-spin state Co3+, which was changed from a high-spin or intermediate-spin state by Al or Ga substitution, reduced the Curie temperature to even 1.5 times lower than the temperature estimated from a simple dilution effect. Al3+ preferentially substituted for intermediate-spin-state Co3+ in the ferrimagnetic CoO6 layer and deteriorated the saturation magnetization of Sr3.1Y0.9Co4O10.5. By contrast, Ga3+ substituted for high-spin-state Co3+ in the CoO6 layer and/or the antiferromagnetic CoO4.25 layer and enhanced the saturation magnetization per Co ion. These results indicate that the magnetic properties of Sr3.1Y0.9Co4O10.5 can be controlled by selectively substituting for Co3+ with different spin states.

Magnetic Refrigeration is an environment-friendly technology when compared to the conventional gas compression system known as vapor compression refrigeration system. Room temperature magnetic refrigeration is a technology which relies on a solid material known as the Magneto-Caloric Material (MCM) which exhibits Magneto-Caloric Effect (MCE) near room temperature. The Magneto-Caloric Effect is the change in temperature of a magnetic material when that material is either magnetized/demagnetized adiabatically. This review is focused on the selection of a suitable MCM which exhibits near-room-temperature MCE. It also explains a methodology to estimate the amount of material required, based on the cooling load or refrigeration capacity (RC) calculation
