Emergence of long-range magnetic order from spin-glass state by tuning electron density in a stoichiometric Ga-based quasicrystal approximant

چکیده
This study reports the first observation of ferromagnetic (FM) order in non-Au-based approximant crystals (ACs) using a novel approach whereby total electron-per-atom (e/a) ratio spin-glass Ga50Pd36Gd14 1/1 AC is lowered by simultaneously substituting certain ratios tri-valent Ga and zero-valent Pd mono-valent Au. The emergence FM this method was confirmed via magnetic susceptibility, magnetization, specific heat measurements. findings open up vast opportunities developing long-range orders from stoichiometric ACs, quasicrystals, even other RKKY compounds with ground state.

Order-disorder transition in a Cd-Ca quasicrystal approximant
Recent experiments discovered an order-disorder transition occuring at very low temperatures in large unit cell approximants of the stable Cd-based binary alloy quasicrystals. The transition is related to correlations among orientational degrees of freedom whose separations are 12 Å. The orientational degrees of freedom represent a type of phason disorder within the unit cells of these large ap...
متن کاملEmergence of long-range order in sheets of magnetic dimers.
Quantum spins placed on the corners of a square lattice can dimerize and form singlets, which then can be transformed into a magnetic state as the interactions between dimers increase beyond threshold. This is a strictly 2D transition in theory, but real-world materials often need the third dimension to stabilize long-range order. We use high pressures to convert sheets of Cu(2+) spin 1/2 dimer...
متن کاملLong-range electron spin-spin interactions from unparticle exchange.
Unparticles as suggested by Georgi are identities that are not constrained by dispersion relations but are governed by their scaling dimension d. Their coupling to particles can result in macroscopic interactions between matter that are generally an inverse nonintegral power of distance. This is totally different from known macroscopic forces. We use the precisely measured long-ranged spin-spin...
متن کاملQuantum critical state in a magnetic quasicrystal.
Quasicrystals are metallic alloys that possess long-range, aperiodic structures with diffraction symmetries forbidden to conventional crystals. Since the discovery of quasicrystals by Schechtman et al. in 1984, there has been considerable progress in resolving their geometric structure. For example, it is well known that the golden ratio of mathematics and art occurs over and over again in thei...
متن کاملEmergence of quasi-long-range order below the Bragg glass transition.
We report small angle neutron scattering rocking-curve measurements of the flux line lattices in the peak effect region in a niobium single crystal. It is found that upon cooling in a magnetic field, the transverse orientational order as well as the longitudinal translational order grow rapidly with decreasing temperature, indicating diminishing population of defects in the ordering vortex matt...
