The Laves phase compound YCo2 is a well-known exchange-enhanced Pauli paramagnet. We report here that, in the nanocrystalline form, this compound interestingly is an itinerant ferromagnet at room temperature with a low coercive field. The magnitude of the saturation moment (about 1μB per formula unit) is large enough to infer that the ferromagnetism is not a surface phenomenon in these nanocrystallites. Since these ferromagnetic nanocrystallites are easy to synthesize with a stable form in air…

Magnetic behavior of nanocrystalline ErCo(2).
It is found that, in these nanocrystallites, Co exhibits ferromagnetic order at room temperature, as inferred from the magnetization data, however, the magnetic transition temperature for the Er sub-lattice remains essentially unaffected suggesting the (Er)4f-Co(3d) coupling is weak on Er magnetism.
Induced magnetic ordering in alloyed compounds based on Pauli paramagnet YCo2
Intermetallic YCo2 compound is a Pauli exchange-enhanced paramagnet. Structural and magnetic properties melt-spun YCo2 pure and alloyed with Nb or Ti are presented. The samples crystallize in
Magnetism of cluster-deposited Y–Co nanoparticles
Nanoparticles of YCo2, YCo3, and YCo5 are produced by cluster-deposition and investigated bothstructurally and magnetically. The nanoparticles have sizes of less than 10 nm and aresuperparamagnetic
Magnetism of fine particles of Kondo lattices, obtained by high-energy ball-milling.
The results of the investigation on the fine particles of some of the alloys obtained by high-energy ball-milling are reviewed to bring out that this synthetic method paves a way to study strong electron correlations in nanocrystals of such alloys.


Magnetism on the surface of the bulk paramagnetic intermetallic compound YCo2.
YCo2 appears to be a prominent candidate to demonstrate the phenomenon of surface-induced itinerant magnetism localized in two dimensions.
Surface ferromagnetism and exchange bias in vacuum annealed Co3−yZnyO4 films
We report on the structural and the magnetic properties of spin coated Co3−yZnyO4 thin films. The microstructure of high vacuum annealed films exhibit a crystalline Zn:CoO core with a disordered
YCo2: intrinsic magnetic surface of a paramagnetic bulk material.
Results of a spin-resolved photoelectron spectroscopic study of YCo2 thin films grown on a W(110) substrate revealed a clear spin-asymmetry probing the validity of the recent theoretical prediction.
Physical properties of RCo2 Laves phases
The large variety of magnetic phenomena observed in the Co based Laves phases are reviewed. Following the band structure calculations it is argued that the outstanding magnetic features of the RCo2
Magnetic properties of amorphous nanocolumns created by heavy ion irradiation of paramagnetic YCo2 thin films (invited)
Recent studies have demonstrated the possibility of inducing amorphous latent tracks in metallic materials by GeV heavy ion irradiation. In the present work, 0.880 GeV 238U beams have been used to
Collective electron metamagnetism
Abstract It is shown, on the basis of the collective electron model, that it may be possible to render certain paramagnetic substances ferromagnetic by the application and subsequent removal of
