Observation of the characteristics of Tm2+ and Tm3+ in homogeneous and inhomogeneous TmSe (1979)
Chouteau, G., Holtzberg, F., Peña, O., Penney, T., Tournier, R.
Susceptibility measurements on the TmySe system (0.79 < y < 1) are presented. Susceptibility under pressure shows no conversion of 2+ ions into 3+ ions.
One impurity effect of Tm in YSe. Kondo effect and Van Vleck behavior (1979)
Berger, A., Haen, P., Holtzberg, F., Lapierre, F., Mignot, J., Penney, T., ...
Low temperature magnetization and resistivity measurements in the dilute TmxY1-xSe system show both Tm2+ and Tm3+ like behavior. However, since the results are nearly linear with concentration, they...
Valence instabilities of Tm in its compounds and solid solutions (1979)
Holtzberg, F., Penney, T., Tournier, R.
TmSe exhibits both non integral valence and antiferromagnetic order in contrast to most other intermediate valence systems which are non magnetic at low temperatures. We report on measurements of...
