• field exhibits a step-like behavior with regions where it increases linearly with VZ (red curves), screening the magnetic field effects, and regions where it remains almost constant as VZ increases (grey curves). This causes the electron fluid to behave in an incompressible or compressible manner

• fields has been very limited. In this review, we compile the two “languages” in an effort to enhance communication. We expect that knowledge of spin chemistry will accelerate progress in spintronics. Keywords: CIDEP; magnetic field effects; photo-CIDNP; radical pairs; triplet states; Review

• reaction the spin multiplicity is changed, spin rules apply and magnetic field effects (MFE), magnetic isotope effects (MIE), as well as electron and nuclear spin polarizations might occur. This is the field of spin chemistry [1][2][3]. The field of spin chemistry emerged with the discovery of anomalous

• , or to be more precise, SCRPs, allow for magnetic-field-dependent chemistry. The radical pair mechanism (RPM) is seen as the key mechanism for magnetic field effects on chemical reactivity. One should note that RPM is not the only mechanism, since, for example, the d-type triplet mechanism and triplet

Keywords: donor/acceptor system; organic magnetoresistance; organic transistors; sign reversal; ultrasmall magnetic field-effects; Introduction In recent years, the development of organic π-conjugated materials have perfectly meet the requirements for low-cost and

• important themes not featured in our previous paper. Further experimental investigations including different mixing compositions reveal a voltage-induced sign reversal and allow the first in-depth study of ultrasmall magnetic-field effects in transistor structures. In particular, the influence of the drain
