A rather general Hamiltonian with long-range Heisenberg exchange and Dzyaloshinskii-Moriya interactions is considered. The continuum limit simplifies the free energy, which contains only a few parameters which in principle are determined by the many parameters of the Hamiltonian, although in practice they may be tuned to fit the experiments. The phase diagram contains a chiral soliton lattice phase and a forced ferromagnetic phase separated by a line of phase transitions, which are of second order at low T and of first order in the vicinity of the zero-field ordering temperature, and are separated by a tricritical point. A highly nonlinear chiral soliton lattice, in which many harmonics contribute appreciably to the spatial modulation of the local magnetic moment, develops only below the tricritical temperature, and in this case, the scaling shows a logarithmic behavior similar to that at T=0, which is a universal feature of the chiral soliton lattice. Below the tricritical temperature, the normalized soliton density curves are found to be independent of T, in agreement with the experimental results of magnetorresistance curves, while above the tricritical temperature they show a noticeable temperature dependence. The implications in the interpretation of experimental results of CrNb3S6 are discussed. 000057095 536__ $$9info:eu-repo/grantAgreement/ES/MINECO/MAT2015-68200-C2-2-P 000057095 540__ $$9info:eu-repo/semantics/openAccess$$aAll rights reserved$$uhttp://www.europeana.eu/rights/rr-f/ 000057095 590__ $$a3.836$$b2016 000057095 591__ $$aPHYSICS, CONDENSED MATTER$$b18 / 67 = 0.269$$c2016$$dQ2$$eT1 000057095 592__ $$a2.339$$b2016 000057095 593__ $$aElectronic, Optical and Magnetic Materials$$c2016$$dQ1 000057095 593__ $$aCondensed Matter Physics$$c2016$$dQ1 000057095 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/publishedVersion 000057095 700__ $$0(orcid)0000-0002-3600-1721$$aCampo, J.$$uUniversidad de Zaragoza 000057095 700__ $$aKousaka, Y. 000057095 7102_ $$12003$$2395$$aUniversidad de Zaragoza$$bDpto.
