Layered bulk solids (MAB phase) and solids with variable crystal structures (antiperovskite carbides, nitrides and carbonitrides) which contain non-critical elements, known or predicted as stable magnetocaloric materials with high magnetization, will be synthesized as powder by using microwave heating and wet chemical-based techniques (sol-gel and liquid ammonia). Guiding principles will be in line with B02, such as manipulating transition temperatures by doping. Further target compounds that have been predicted (A05) as stable magnetocalorics (Fe3AlB4, Fe3CoB2, Mn3SnC, Co3GaN) will be included (B05) and magnetically characterized (B01).

含有非临界元素的层状块状固体(MAB相)和具有可变晶体结构的固体(反钙钛矿碳化物、氮化物和碳氮化物)将通过微波加热和湿化学法(溶胶凝胶法和液氨法)制备成粉末。指导原则将与B02一致，例如通过掺杂来操纵转变温度。被预测为稳定的磁热化合物(Fe3AlB4，Fe3CoB2，Mn3SnC，Co3GaN)的目标化合物(A05)将包括(B05)和磁性表征(B01)。
