Description

Ternary orthorhombic aluminides of RT2Al10 type (R:Ce, Yb, T: Fe, Ru, Os) are currently attracting much interest because of a number of exotic properties such as anomalously high magnetic ordering temperatures in CeRu2Al10 and CeOs2Al10, and strongly hybridized Kondo insulating state in CeFe2Al10. The Fe-Al systems are of special interest because YFe2Al10 is claimed being located close to a Fe-based ferromagnetic instability at very low temperature. Here pronounced non Fermi liquid (NFL) phenomena are observed. For YbRh2Si2 this NFL behaviour is associated to strong ferromagnetic fluctuations (see 29Si NMR). Our spin relaxation study on YFe2Al10 gives strong evidence for Fe based ferromagnetic fluctuations evolving towards low temperature in small fields. YbFe2Al10 is a weak Kondo coupled heavy fermion system where no traces of Fe-magnetism could be found.
