    The spin glass/cluster glass properties of manganite perovskites Y1 - x + yCax - yMn1 - yCryO3, x=0.3, y=0 and x=0.4, y=0.05, 0.1 were studied by measuring and analyzing magnetization, AC susceptibility and heat capacity data. While the x=0.3, y=0 sample shows typical spin glass characteristics, the Cr-doped manganites (x=0.4) can be rather viewed as non-uniform systems with ferromagnetic clusters

    Vlastnosti spinového skla/klastrového skla v manganitových perovskitech Y1 - x + yCax - yMn1 - yCryO3, x=0.3, y=0 and x=0.4, y=0.05, 0.1 byly studovány měřením a analýzou dat magnetizace, AC susceptibility and specifického tepla. Zatímco vzorek x=0.3, y=0 vykazuje charakteristiky typické pro spinové sklo, jeví se manganity dopované Cr (x=0.4) spíše jako nehomogenní systémy s feromagnetickými klastry
