The compound crystallizes in the cubic Laves phase C15 structure at high temperature, undergoes a tetragonal distortion (space group I4l/amd) around T(C)approximate to 100 K and an orthorhombic distortion (space group Fddd) at T 42 K. The temperature dependence of lattice constants, magnetostriction constant, and magnetic moment indicate that the magnetic and structural transitions are second order in the vicinity of T-C and are first-order around 42 K. Refinements of magnetic structure reveal that the Nd moment distinctly exhibits an abrupt increase at the first-order transition and the easy magnetization direction of the compound changes from [001] in the tetragonal lattice to [011] in the orthorhombic lattice, indicating a strong coupling between crystal structure and magnetic properties at zero field. Analysis of the temperature dependence of bondlength suggests a strong magnetic exchange striction in the tetragonal structure and that the abrupt increase of the Nd moment is attributed essentially to a change in crystal electric field. Field-dependent neutron diffraction reveals a decoupling of the magnetic and structural transitions under relatively modest magnetic fields.","authors":[],"categoryName":"|","doi":"","fpage":"","id":"402d51f4-0d48-433b-b470-27ef46127306","issue":"6","journal":{"abbrevTitle":"PRB","id":"48ba155b-d6de-484c-bd85-973be949b8c5","issnPpub":"1098-0121","publisherId":"PRB","title":"Physical Review B"},"keywords":[{"id":"ca19edca-fcb8-4d59-9306-08cd47887a9a","keyword":"itinerant-electron metamagnetism;neutron powder-diffraction;intermetallic compounds;exchange;heavy;light;hoco2;order","originalKeyword":"itinerant-electron metamagnetism;neutron powder-diffraction;intermetallic compounds;exchange;heavy;light;hoco2;order"}],"language":"en","publisherId":"1098-0121_2005_6_1","title":"Magnetic structure, magnetostriction, and magnetic transitions of the Laves-phase compound NdCO2","volume":"71","year":"2005"},{"abstractinfo":"Crystal structure, magnetic properties and magnetostriction of Dy0.7Pr0.3(Fe1-xBx)(2) (0less than or equal toxless than or equal to0.20) have been investigated by means of x-ray diffraction, ac initial susceptibility, a vibrating sample magnetometer, and a standard strain technique. The matrix of Dy0.7Pr0.3Fe2 alloy consists of (Dy,Pr)Fe-2 phase with a cubic MgCu2-type structure and some amount of (Dy,Pr)Fe-3 phase with a rhombohedral PuNi3-type structure. The introduction of boron effectively restrains the emergence of the iron-rich phase and thus decreases the amount of (Dy,Pr)Fe-3 phase. Dy0.7Pr0.3(Fe1-xBx)(2) alloy with x=0.05 contains small amount of (Dy,Pr)(Fe,B)(3) phase, and those with x=0.10 and x=0.15 are essentially of a single (Dy,Pr)(Fe,B)(2) phase. An unidentified minor phase appears when x=0.20. The lattice parameter of (Dy,Pr)(Fe,B)(2) phase decreases monotonically with the boron substitution up to x=0.20, indicating that the boron atoms occupy the substitutional sites. The Curie temperature for (Dy,Pr)(Fe,B)(2) phase obviously increases compared with the boron free one. The saturation magnetization at room temperature increases with increasing boron content for the alloys studied, suggesting that the partial boron substitution is beneficial to the increment of the exchange interactions in the Dy0.7Pr0.3Fe2 system. The increment of the magnetization originates from the decrement of iron content, because the Fe moment that aligns antiparallel with the Dy moment almost keeps constant in this system. Boron substitution for iron increases the lattice distortion and anisotropy, thus causes the decrease of the linear magnetostriction lambda(a)=lambda(parallel to)-lambda(perpendicular to) at the room temperature.

With increasing V content, the magnetic main phase in the Pr10Fe76V6+yB8-y series changes from the Pr2Fe14B-type phase via a metastable Pr(Fe,V, B)(7) phase with TbCu7-type structure to Pr(Fe,V, B)(12) phase with ThMn12-type structure.
