Spinska stekla : diplomski seminar na bolonjskem študijskem programu 1. stopnje FizikaOrnik, JanV diplomskem seminarju obravnavamo magnetne lastnosti kanoničnega spinskega stekla Cu94Mn6. Iz meritev temperaturne odvisnosti susceptibilnosti v konstantnem majhnem magnetnem polju določimo ... temperaturo zamrznitve. Meritvam nad temperaturo zamrznitve prilagodimo Curie-Weissov zakon in izračunamo efektivni magnetni moment. Izmerimo tudi magnetizacijo vzorca v magnetnem polju do 5 T in opazimo histerezno obnašanje. Iz meritev susceptibilnosti v izmeničnem magnetnem polju izračunamo faktor spremembe temperature zamrznitve s spremembo frekvence izmeničnega polja, ki jih opišemo tudi z empiričnim Vogel-Fulcherjevim modelom.Type of material - undergraduate thesis ; adult, seriousPublication and manufacture - Maribor : [J.
