Why rare-earth ferromagnets are so rare: insights from the p-wave Kondo model [PDF]
, 2017 Magnetic exchange in Kondo lattice systems is of the Ruderman-Kittel-Kasuya-Yosida type, whose sign depends on the Fermi wave vector, $k_F$ . In the simplest setting, for small $k_F$ , the interaction is predominately ferromagnetic, whereas it turns more

The Influence Of Neutron Capture Rates On The Rare Earth Region Of The r-Process Abundance Pattern
, 2012 We study the sensitivity of the r-process abundance pattern to neutron capture rates along the rare earth region (A~150 to A~180). We introduce the concepts of large nuclear flow and flow saturation which determine the neutron capture rates that are ...

Observation of the novel type of ordering: Spontaneous ferriquadrupolar order
, 2018 Using Raman and infrared spectroscopies the spontaneous ferriquadrupolar ordering has been observed in the rare-earth-based system KDy(MoO$_4$)$_2$. Ordered quadrupoles in the electron subsystem attend non-equivalent distortions of rare-earth ions in the
