We report the results of measurements of the low-temperature specific heat C<Subscript>p</Subscript>(T) and the ac susceptibility χ<Subscript>ac</Subscript>(T) in low applied magnetic fields for a series of samples of Eu<Subscript>1-x</Subscript>Ca<Subscript>x</Subscript>B<Subscript>6</Subsc ript>. The anomalies in C<Subscript>p</Subscript>(T), together with the results for χ<Subscript>ac</Subscript>(T) and M(H), confirm the onset of phase transitions...</subscript></subscript><//subsc></subscript></subscript></subscript></subscript></subscript>

We investigated the stability of magnetic moments in Al<Subscript>69.8</Subscript>Pd<Subscript>12.1</Subscript>Mn<Subscript>18. 1</Subscript>. This alloy exists in both, the icosahedral (i) and the decagonal (d) quasicrystalline form. The transition from the i- to the d-phase is achieved by a simple heat treatment. We present the results of measurements of the...</superscript></subscript></subscript></subscript>
