Description
Изобретение относитс к технике радиоизмерений.This invention relates to a radio measurement technique.
Цель изобретени - повьшение-точности и упрощение.The purpose of the invention is poverness and simplification.
Способ определени направлени магнитной компоненты СВЧ-пол в объемном резонаторе реализуетс следующим образом.The method of determining the direction of the magnetic component of the microwave field in a cavity resonator is implemented as follows.
Способ основан на применении электронного парамагнитного резонанса (ЭПР) с использованием радиоспектрометра , включающим воздействие на пара- магнитньпЧ образец статического магнитного пол и перпендикул рного к нему СВЧ и наблюдение -линий ЭПР. В качестве парамагнитного образца используют монокристалл ромбической симметрии и по таблице соотношени интенсивностей линий электронного парамагнитного резонанса определ ют угол магнитной компоненты СВЧ-пол по отношению к ос м парамагнитных центровThe method is based on the use of electron paramagnetic resonance (EPR) using a radio spectrometer, which includes an effect on a paramagnetic sample of a static magnetic field and a microwave perpendicular to it and the observation of EPR lines. A single crystal of orthorhombic symmetry is used as a paramagnetic sample, and the angle of the magnetic component of the microwave field with respect to the axes of the paramagnetic centers is determined from the table of the ratio of the intensities of the electron paramagnetic resonance lines.
и производ т уточнение направлени магнитной компоненты СВЧ-по-п расстройкой образца на несколько граду- сов. Поскольку найденный по таблице угол по отношению к ос м парамагнитных центров не дает информацию, в каком квадранте расположен вектор магнитной компоненты СВЧ-пол , примен етс расстройка образца. При этом учитываетс знак изменени интенсивности линии ЭПР, определ ющий тфиближаетс ли ось центра к направлению магнитной компоненты СВЧ-пол .and clarifying the direction of the magnetic component of the microwave by detuning the sample by several degrees. Since the angle found on the table with respect to the axes of the paramagnetic centers does not provide information on which quadrant the vector of the magnetic component of the microwave field is located, the sample detuning is used. This takes into account the sign of the change in the intensity of the EPR line, which determines whether the axis of the center approaches the direction of the magnetic component of the microwave field.
Выбор образца в виде монокристалла ромбической симметрии обусловлен необходимостью получени отличающихс интенсивностей линии ЭПР при различных ориентаци х СВЧ и устранени вращени кристалла дл определени , какой угол составл ет Н с ос ми парамагнит-. нь1Х центров.The choice of a sample in the form of a single crystal of orthorhombic symmetry is due to the need to obtain different intensities of the EPR line with different microwave orientations and eliminate the rotation of the crystal to determine what angle H is with the paramagnetic – axis. h1 centers.
