About the possibility to observe induced superparamagnetism

The possibility for observation of superparamagnetism of ultrafine particles at temperatures Т above their Curie point Тc { "induced superparamagnetism") is discussed. The experimental conditions for observing this phenomenon have bееn analyzed within the framework of Langevin's model complemented with the molecular field theory. The assessments show that to observe "induced superparamagnetism" the easily attainable fields are required.
