A new type of antiferromagnetic CoAl2O4 coated ferromagnetic Co solid solution is synthesized by arc-discharging. Typical HRTEM images show that the nanocapsules form in a core-shell structure. The size of the nanocapsules is in range of 10-90 nm and the thickness of the shell is about 3-10 nm. X-ray photoelectron spectrum (XPS) and X-ray diffraction (XRD) reveal that the core consists of Co solid solution, while the shell is CoAl2O4. The magnetic field and temperature dependence of magnetizations confirm that the Co solid solution nanocapsules are basically in the ferromagnetic state below Curie temperature. In addition, the antiferromagnetic order occurs with Neél temperature TN of about 5 K. The saturation magnetization of Ms = 76.1 Am2/kg and the coercive force of Hc= 23.28 kA/m are achieved at room temperature for the Co solid solution nanocapsules.

A fully dense TaC ceramic was prepared by hot pressing using 10 mol% ZrC plus 5 mol% Cu as a sintering aid. Formation of (Ta, Zr)C solid solution (ss) by reaction between TaC and ZrC facilitated densification. Addition of Cu refined the microstructure and consequently improved flexural strength of the TaC ceramics. TEM investigation found ubiquitous precipitation of nanocrystallites at multigrain conjunctions. The nanocrystallites were (Ta, Zr)C solid solution with uniform dispersion in an oxygen-rich glassy matrix. Although formation of nanoprecipitates may not much affect the mechanical properties of the TaC ceramic, the structure suggested a new type of nanoceramic worth further research.

The solid solution KNi0.93FeII0.07FeIII(PO4)2{potassium [nickel(II)/iron(II)] iron(III) bis(orthophosphate)} has been prepared by the flux method. The compound shows a new type of structure for a phosphate with the general compositionMIMIIMIII(PO4)2. The framework is formed by [(Ni/Fe)O6] polyhedra [Fe site occupancy = 0.069 (14)] linkedviashared oxygen vertices forming acis-like parallel chain stretching alongaand [FeO5] polyhedra (located on alternate sides of the chains) connectedviatwo types of PO4groups into a three-dimensional structure. The K atoms are disordered between two sites, denoted K1Aand K1B, with occupancies of 0.930 (9) and 0.070 (9), respectively, and reside inside channels along theaaxis. Calculations of the Voronoi–Dirichlet polyhedra of the K atoms give a coordination scheme for K1Aof [9 + 3] and for K1Bof [10 + 2]. The most remarkable feature of the structure is the splitting of the K-atom site and the population of the K1Aand K1Bpositions due to substitution of Ni by Fe in the (Ni/Fe) position.
