Hydrostatic and chemical pressure are efficient stimuli to alter the crystal structure and are commonly used for tuning electronic and magnetic properties in materials science. However, chemical pressure is difficult to quantify and a clear correspondence between these two types of pressure is still lacking. Here, we study intermetallic candidates for a permanent magnet with a negative thermal expansion (NTE). Based on in situ synchrotron X-ray diffraction, negative chemical pressure is revealed in Ho$$_2$$Fe$$_{17}$$ on Al doping and quantitatively evaluated by using temperature and pressure dependence of unit cell volume. A combination of magnetization and neutron diffraction measurements also allowed one to compare the effect of chemical pressure on magnetic ordering with that of hydrostatic pressure. Intriguingly, pressure can be used to control suppression and enhancement of NTE. Electronic structure calculations indicate that pressure affected the top of the majority band with respect to the Fermi level, which has implications for the magnetic stability, which in turn plays a critical role in modulating magnetism and NTE. This work presents a good example of understanding the effect of pressure and utilizing it to control properties of functional materials.

The ion hydration and association and hydrogen-bonded water structure in an aqueous 3 mol/kg RbCl solution were investigated at 298 K/0.1 MPa, 298 K/1 GPa, 523 K/1 GPa, and 523 K/4 GPa by neutron diffraction combined with EPSR methods. The second hydration layer of Rb$$^+$$ and Cl$$^-$$ becomes evident under elevated pressure and temperature conditions. The average oxygen coordination number of Rb$$^+$$ (Cl$$^-$$) in the first hydration layer increases from 6.3 (5.9) ambient pressure to 8.9 (9.1) at 4 GPa, while decreasing coordination distance from 0.290 nm (0.322 nm) to 0.288 nm (0.314 nm). The orientation of the water dipole in the first solvation shell of Rb$$^+$$ and a central water molecule is sensitive to pressure, but that in the first solvation shell of Cl$$^-$$ does not change very much. The number of contact-ion pairs Rb$$^+$$-Cl$$^-$$ decreases with elevated temperature and increases with elevated pressure. Water molecules are closely packed, and the tetrahedral hydrogen-bonded network of water molecules no longer exists in extreme conditions.

The mass spectrum and strong decays of the S-wave $$bar c bar s qq$$ states are studied in the compact tetraquark scenario with the quark model. The model consists of the Coulomb, the linear confinement, and the hyperfine interactions. We calculate their decay amplitudes into the $$D^{-(*)}K^{(*)}$$ channels using the quark interchange method. The mass and decay width of the $$I(J^P)=1(0^+)$$ state are $$M = 2941$$ MeV and $$Gamma_X=26.6$$ MeV, respectively, which indicates that it might be a good candidate for the recently observed $$X^0(2900)$$ state. We also obtain an isospin partner state $$I(J^P)= 0(0^+)$$ with $$M =2649$$ MeV and $$Gamma_{Xto D^- K}= 48.1$$ MeV, respectively. Future experimental search for $$X(2649)$$ will be very helpful.

The temperature and energy dependence of spin excitations in an optimally P-doped BaFe$$_2$$(As$$_{0.7}$$P$$_{0.3}$$)$$_2$$ superconductor (T$$_c$$ = 30 K) were studied by using inelastic neutron scattering. Experimental results are consistent with calculations from a combined density functional theory and dynamical mean field theory, and suggest that the decreased average pnictogen height in BaFe$$_2$$(As$$_{0.7}$$P$$_{0.3}$$)$$_2$$ reduces the strength of electron correlations and increases the effective bandwidth of magnetic excitation.
