چکیده

The synthesis and characterization of the vanadium-based kagome metal TbV${_6}$Sn${_6}$ is presented. X-ray measurements confirm this material forms with same crystal structure type as recently investigated metals GdV$_6$Sn$_6$ YV$_6$Sn$_6$, space group symmetry P6/mmm. A signature a phase transition at 4.1K observed in heat capacity, resistivity, magnetic susceptibility measurements, both resistivity magnetization exhibit hysteresis field. Furthermore, strikingly large anisotropy was observed, c-axis nearly 100 times ab plane 2K. This highly suggestive uniaxial ferromagnetism, size 9.4$\mu_b$/f.u. indicates Tb$^{3+}$ $4f$ electronic moments cooperatively align perpendicular to V lattice plane. entropy Rln(2), indicating that CEF ground state ion doublet, therefore sublattice electrons can be shown map low temperatures Ising model D$_{6h}$ environment. Hall from 300K 1.7K described by two-band carrier transport below around 150K, increase hole electron mobilities, similar an anomalous effect seen ordering temperature. Angle-resolved photoemission above temperature reveal typical dispersions. Our study presents ideal system interplay between ferromagnetism non-trivial states emerging lattice.

Ferromagnetism in Transitional Metal-Doped MoS2 Monolayer.

Manipulating electronic and magnetic properties of two-dimensional (2D) transitional-metal dichalcogenides (TMDs) MX2 by doping has raised a lot of attention recently. By performing the first-principles calculations, we have investigated the structural, electronic, and magnetic properties of transitional metal (TM)-doped MoS2 at low and high impurity concentrations. Our calculation result indic...

Kondo metal and ferrimagnetic insulator on the triangular kagome lattice.

We obtain the rich phase diagrams in the Hubbard model on the triangular kagome lattice as a function of interaction, temperature, and asymmetry by combining the cellular dynamical mean-field theory with the continuous time quantum Monte Carlo method. The phase diagrams show the asymmetry separates the critical points in the Mott transition of two sublattices on the triangular kagome lattice an...

Ferromagnetism and metal-insulator transition in the disordered Hubbard model.

A detailed study of the paramagnetic to ferromagnetic phase transition in the one-band Hubbard model in the presence of binary-alloy disorder is presented. The influence of the disorder (with concentrations x and 1-x of the two alloy ions) on the Curie temperature T(c) is found to depend strongly on electron density n. While at high densities, n>x, the disorder always reduces T(c); at low densi...

A search for ferromagnetism in transition-metal-doped piezoelectric ZnO

We present the results of a computational study of ZnO in the presence of Co and Mn substitutional impurities. The goal of our work is to identify potential ferromagnetic ground states within the (Zn,Co)O or (Zn,Mn)O material systems that are also good candidates for piezoelectricity. We find that, in contrast to previous results, robust ferromagnetism is not obtained by substitution of Co or M...

Non-DMS related ferromagnetism in transition metal doped zinc oxide

We review pitfalls in recent efforts to make a conventional semiconductor, namely ZnO, ferromagnetic by means of doping with transition metal ions. Since the solubility of those elements is rather low, formation of secondary phases and the creation of defects upon low temperature processing can lead to unwanted magnetic effects. Among others, ion implantation is a method of doping, which is hig...
