Title: Structural and double magnetic transitions in the frustrated spin- 1 2 capped-kagome antiferromagnet ( RbCl ) Cu 5 P 2 O 10

Abstract

The structural and magnetic properties of the geometrically frustrated spin- 1 2 capped-kagome antiferromagnet (RbCl) Cu₅P₂O₁₀ are investigated via temperature-dependent x-ray diffraction, magnetization, heat capacity, and ³¹P NMR experiments on a polycrystalline sample. It undergoes a structural transition at around T_t ≃ 310 K from a high-temperature trigonal (P ¯3m1) to a low-temperature monoclinic (C2/c) unit cell, where the low-temperature structure features the capped-kagome geometry of Cu²⁺ ions. Interestingly, it shows the onset of two successive magnetic transitions at T_N1 ≃ 20 K and T_N2 ≃ 7 K. The shape of the ³¹P NMR spectra unfolds the possible nature of the transitions below T_N1 and T_N2 to be of incommensurate and commensurate antiferromagnetic type, respectively. A large value of the Curie-Weiss temperature as compared to T_N1 sets the frustration parameter f ≃ 8, ensuring strong magnetic frustration in the compound. From the ³¹P NMR spin-lattice relaxation rate, the leading antiferromagnetic exchange coupling is estimated to be J/k_B ≃ 117 K. Furthermore, these unusual double magnetic transitions make this compound beguiling for further investigations.

Microscopic characterization of the magnetic properties of the itinerant antiferromagnet La 2 Ni 7 by La 139 NMR/NQR measurements

Journal Article Ding, Qing -Ping ; Babu, Joyal ; Rana, K. ; ... - Physical Review. B

In this study, ¹³⁹La nuclear magnetic resonance (NMR) and nuclear quadrupole resonance (NQR) measurements have been performed to investigate the magnetic properties of the itinerant magnet La₂Ni₇, which shows a series of antiferromagnetic (AFM) phase transitions at T_N1= 61 K, T_N2 = 56 K, and T_N3 = 42 K under zero magnetic field. Two distinct La NMR signals were observed due to the two crystallographically inequivalent La sites in La₂Ni₇ (La1 and La2 in the La₂ Ni₄ and the LaNi₅ subunits of the La₂Ni₇unit cell, respectively). From the ¹³⁹La NQR spectrum in the AFM state below T_N3, the AFMmore »« less

Long-range three-dimensional magnetic structures of the spin S =1 hexamer cluster fedotovite-like A 2 Cu 3 O ( SO 4 ) 3 ( A 2 = K 2 , NaK, Na 2 ): A neutron diffraction study

Journal Article Pomjakushin, V. Yu. ; Podlesnyak, Andrey A. ; Furrer, Albert ; ... - Physical Review. B

The crystal and magnetic structures of the spin S = 1 hexamer cluster fedotovite-like A₂ Cu₃ O(SO₄)₃ (A₂ = K₂, NaK, Na₂) were studied by neutron powder diffraction at temperatures 1.6–290 K. The crystal structures in all compounds are well refined in the monoclinic space group C2/c. The basic magnetic units of the compounds are copper hexamers, which are coupled by weak superexchange interactions giving rise to three-dimensional long-range magnetic order below 3.0 < T_N < 4.7 K. We have found that for A₂ = K₂ and NaK the propagation vector of the magnetic structure is k = [0,0,0], and the coupling of the Cu hexamers is ferromagnetic (FM) along the ab diagonal and antiferromagnetic along the bc diagonal. In contrast, for A = Na the propagation vector is k = [0,1,0], and the Cu hexamers are coupled antiferromagnetically (AFM) along the ab diagonal. Further, the hexamers are formed by three Cu pairs arranged along the b axis. The calculated spin expectation valuesmore »« less

Interrelationships between nematicity, antiferromagnetic spin fluctuations, and superconductivity: Role of hotspots in FeSe 1 - x S x revealed by high pressure Se 77 NMR study

Journal Article Rana, K. ; Ambika, D. V. ; Bud'ko, S. L. ; ... - Physical Review. B

The sulfur-substituted FeSe, FeSe_1-xS_x, is one of the unique systems that provides an independent tunability of nematicity, antiferromagnetism, and superconductivity under pressure (p). Recently, Rana et al. [K. Rana et al., Phys. Rev. B 101, 180503(R) (2020)] reported, from ⁷⁷Se nuclear magnetic resonance (NMR) measurements on FeSe_0.91S_0.09 under pressure, that there exists a clear role of nematicity in the relationship between antiferromagnetic (AFM) spin fluctuations and the superconducting transition temperature (T_c), where the AFM spin fluctuations are more effective in enhancing T_c in the absence of nematicity than with nematicity. Here, motivated by the work, we carried out ⁷⁷Se NMRmore »« less
