We report here a simple hydrothermal synthesis of 100-200 nm flakes of tochilinite (Fe1 xS)n(Mg,Fe)(OH)2 constructed by interchanging atomic sulfide and hydroxide sheets as a representative of a new platform...
SmFe 3 (BO 3) 4 single crystals have been grown from the bismuth trimolybdate and lithium tungstate-based melt-solutions. Samarium ferroborate single crystals were grown first from the lithium-tungstate flux. The magnetic and magnetoelectric properties of the synthesized crystals have been compared. It is shown that the SmFe 3 (BO 3) 4 ferroborate grown from the bismuth trimolybdate-based melt-solution contains impurities of Bi 3+ ions (5% at.), which replace Sm 3+ ions, while the SmFe 3 (BO 3) 4 , ferroborate grown from the lithium tungstate-based melt-solution contains minor or zero amounts of such impurities. The magnetoelectric and magnetodielectric effects with the Bi 3+ admixture appeared 1.5x stronger than in SmFe 3 (BO 3) 4 ; this is probably due to twinning.

In a metal-insulator-semiconductor diode with the Schottky barrier fabricated on the basis of the Fe/SiO 2 /n-Si structure, a drastic change in the impedance in an applied magnetic field was found. The maximum value of this effect was observed at temperatures of 10-30 K in the frequency range of 10 Hz-1 MHz where the ac magnetoresistance and magnetoreactance ratios exceeded 300% and 600%, respectively. In the low-frequency region (<1 kHz), these ratios could be controlled in wide range by applying bias to the device. The main contribution to the impedance when measured at temperatures corresponding to the strongest magnetic-field sensitivity comes from the interface states localized near the SiO 2 /n-Si interface and the processes of their recharging in an applied ac voltage. The applied magnetic field changes the energy structure of the interface states, thus affecting the processes of the charging dynamics. V C 2014 AIP Publishing LLC. [http://dx.
