Structural, electric and magnetic measurements have been performed on the new rare earth intermetallic compound Gd2Ni2Cd. It crystallises in the Mn2B2Al-type structure (space group Cmmm) and undergoes an antiferromagnetic transition at 65 K. Above 70 K the compound follows the Curie-Weiss law with μ = 8.03 μB and θ = + 22 K. The transition is...

The electronic anisotropy in MgB2, which arises from its layered crystal structure, is not completely clear until now. High quality c-oriented films offer the opportunity of studying such property. MgB2 thin films were deposited by using two methods both based on room temperature precursor deposition (by pulsed laser ablation) and ex situ...

We describe a computational approach for the automaticrecognition and classification of atomic species in scanningtunnelling microscopy images. The approach is based on apipeline of image processing methods in which the classifica-tion step is performed by means of a Fuzzy Clustering algo-rithm. As a representative example, we use the...

R11Ni4In9 (R = rare earth) compounds exhibit an unusual self-assembled nano/microfibrous morphology that results in anisotropic structural and magnetic behaviors. The existence of new compounds for R = Dy, Ho, Er, Tm and Lu, has been established (orthorhombic Nd11Pd4In9- type, oC48, Cmmm, Z = 2), showing that the formation of these phases,...

Fe content plays a primary role in the structural, magnetic and transport properties of Fe(Se,Te) compounds. In this work we investigate some of these properties in ipo-stoichiometric FeySe0.5Te0.5 samples (y 6 1.00) prepared by a novel synthesis technique, involving a melting process. These samples are characterized by a pore-free...
